Caryospora matatu n. sp. is the first species of coccidia reported from the a horned bush viper, Atheris ceralophorus endemic to Tanzania. Oocysts are spherical or slightly subspherical, 19.8 (16-23) µm, a micropyle and an oocyst residuum are absent, a single polar granule is present. An oocyst wall is bilayered, ~ 1.5 µm thick, brownish and distinctly pitted. Sporocysts are ellipsoidal, 15.6 (12.5-17.0) x 10.1 (8-12) µm, tightly fitting an internal oocyst diameter, Stieda and substieda bodies are present. An experimental inoculation of SCID mice did not confirm a facultatively heteroxenous life cycle in the studied coccidium. Morphology and evolutionary history of Caryospora species from viperids is is reviewed and discussed.
Résumé
Caryospora matatu n. sp. est la première coccidie rapportée chez la vipère à corne Atheris ceratophorus, endémique en Tanzanie. Les oocystes sont sphériques ou légèrement subsphériques, de 19,8 µm (16-23), sans mycropyle et sans résidu d'oocyste, un granule polaire unique est présent. La paroi de l'oocyste est double, d'environ 1,5 µm d'épaisseur, brunâtre et distinctement excavée. Les sporocystes sont ellipsoïdes, de 15,6 (12,5-17,0) x 10,1 (8-12) µm, remplissant l'ooyste ; le corps et le sous-corps de Stieda sont présents. Une inoculation expérimentale de souris SCID ne confirme pas la possibilité d'un cycle hétéroxène chez la coccidie étudiée. La morphologie et l'évolution des Caryospora des vipères sont revues et discutées.
